• In the new Windows 10 May 2020 Update, Microsoft introduces a new security feature to protect your PC from potentially unwanted applications in Windows 10.
  • The new security feature offers protection against PUAs, but it is not enabled by default at this time. Read our guide below to learn how.
  • If you need more information about Windows Defender, go directly to our Microsoft Windows Defender section.
  • Security is essential today when all kinds of Internet threats are triggered. Read more information about how to protect yourself on our Security Hub.

Malware, ransomware, and spyware have increased in the last two months, so you need to be very careful when protecting your data. Microsoft took twice as long to patch security issues and now it has become a priority.

Windows Defender is also updated fairly frequently and has improved protection against new threats. Also, in the next major feature update, the new Windows 10 May 2020 update, Microsoft introduces a new security feature to protect your PC from potentially unwanted applications in Windows 10.

The first rule of Internet safety is never to download applications with a bad reputation from where you find them free.

This is because many of them come with potentially unwanted applications (PUAs) and if you run them, you will start to see the consequences: pop-up ads, the system is slowing down, and suddenly the search engine in your browser changes.

Microsoft introduces with Windows 10 May 2020 a new reputation-based protection feature in the Windows security application. The new security feature offers protection against PUAs, but it is not enabled by default at this time.

How can I block potentially unwanted apps in Windows 10?

If you want to activate PUA protection and block it in Windows 10, follow these steps:

1. Type Reputation in the Windows search box and click the protection based in Reputation in the results.

2. Next, click on application and browser control and reputation-based protection settings. Now click the button to turn on the potentially unwanted application blocking settings as in the image below.

Once you activate the feature, the Windows security app will block adware, cryptocurrency miners, and other unwanted scam apps that can be bundled with your free software downloads.

The Windows security application will also allow you to manage PUA protection and block or allow applications, downloads, or both. It is good to know that this feature is also included in Microsoft Edge browsers, so Windows Defender will automatically search for PUAs as the application is downloaded in the browser.

For Chromium-based Microsoft Edge, you will need to enable PUA protection manually. Just open Edge settings and go to the Privacy and services section. Then scroll down until you find Services and turn on the option Block potentially unwanted applications .

In fact, we have tried downloading some known suspicious adware applications to see how it works and it still does not work.
